Now and then an account gets suspended. If yours is, you'll see it when you sign in — a notice that your account is suspended, with the reason. This page explains what that looks like and how to appeal. It's short, because the honest answer is short: you get told why, and you get a way to write back.
A suspended account can't be used the normal way. Instead, you'll find a message thread with the team — each message shows who sent it and when. The first message is from us, with the reason for the suspension. If a duration was set, the suspension lifts on its own when it ends; some are open-ended until they're resolved.
If you think the suspension is a mistake, or you've fixed whatever caused it, reply in that thread. Write your appeal as a message and send it. It's added to the thread, and someone on the team reads it and replies there. Everything stays in one place — your message, our reply, and anything after that. There's no separate form to hunt down.
Write a message in the suspension thread on your account and send it. The team reads it and replies in the same thread.
If it was set with a duration, yes — it lifts when the duration is up. Otherwise it stays until it's resolved through the thread.
In the first message of the thread. It's from the team and it states why the account was suspended.
